Visualizing telemetry using Grafana

Grafana is open source software used for the visualization of telemetry data. It provides an easy-to-use and interactive option for visualizing observability metrics.

Istio installation provides sample manifests for Grafana, located in samples/addons. Install Grafana using the following commands:

% kubectl apply -f samples/addons/grafana.yaml
serviceaccount/grafana created
configmap/grafana created
service/grafana created
deployment.apps/grafana created
configmap/istio-grafana-dashboards created
configmap/istio-services-grafana-dashboards created

% istioctl dashboard grafana
http://localhost:3000
